    Sine, Cosine and Tangent

    Opposite & adjacent sides and SOHCAHTOA of angles

    The Sine, Cosine and Tangent functions express the ratios of sides of a right triangle. See below for greater detail
    Sine Function
    The sine of an angle is always the ratio of the (opposite side)/(hypotenuse).
      Sine of ABC=AC /AB
     
    (opposite side)/(hypotenuse)

    Cosine Function
    The cosine of an angle is always the ratio of the (adjacent side/ hypotenuse)
    The cosine of ABC =CB/AB
    (adjacent side)/(hypotenuse)

    Tangent Function
    The tangent of an angle is always the ratio of the (opposite side)/(adjacent side)
    The tangent of ABC =AC/ CB
    Practice Identifying Adjacent and Opposite Sides
